Newborn!!

My little boy is three days old! Hubs was going from the cradle position with him to sitting him up on his chest to burp him and his head flopped a bit, I had to explain how his head needed more support. Baby should be fine with a small head flop right? I’m super anxious and yes can be over bearing, just want things to be perfect (even though that is unrealistic) will make sure head is more supported! But that one flop won’t cause damage right?
